ENGINE-STARTER.

State of Nen' York, have invented n certain newand uselul Improvement inEngine-Starters, oi which thel folloiving is a specification, referencebeing had therein.

' to the accompanying drawings, forming. part thereof.

My invention relates generally to starting devices for.- in tcrnalcombustion engines, more particularly engines such as are used onautomobiles 'or motor boats, and has 'for its objects simplicity ofconstruction, and convenicnce, simplicity and efficiency of operation.

I provide a manually controllable valve for admitting compressed airfrom a reservoir to the air intake conduit of the carburetor, thecommunication of the air intake ol the carburetor with the outer airbeing closed at this time by a valve provided for the purpose, so thatthe air' iindcr pressure from the reservoir passes through thecarburetor, vaporizing' the suiliciently volatile liquid fuel suppliedto the carbureter. The combustible mix- ,ture thence passes to theworking cylinders .of the engine and into and through all of thecylinders until the former and more or less iucombustiblecontents o thecylinders are driven out and replaced by the combusti ble mixture orpriming, inlets to and outlets from the 'cylinders being opened for thispurpose by manually controllable means. Means are provided forpreventing the operation of the' sparking devices or ignition devicesduring the time that 'the cylinders are receiving their priming. In'thepreferred form of my invention, ior ordinary running, a fuel isusedwhich islcss volatile than could bo efficiently used for starting or'iorrunning .while the carburetor is yet cold. In this preferredconstruction means. are provided for 'supplying the car- 'bureter with amore -volntile f u el Ior starting and for ru'nning until the lessvolatile fuel can be-vaporizedbythe carhureter, such as is the subjectof4 my prior ap'plication, Ser-inl Number 349,277, Bled.

The engine then starts by the ignition of thc priming charge andcontinues to run by drawing atmospheric air through the carburetor inthe usual manner.

My invention includes means for introducing priming 'of combustiblemixture into all of theengine cylinders concurrently and fOrpassing-suchpriming through the cylinders until tlie cylinders have become filledwith the priming and the previous contents of the cylinders have beensubstantially displaced:

My invention also includes mearis for elccting'sucli priming from aselected one of a plurality of sources of volatile fuel, whereby thecylinders may be primed for the starting operation with a hipi grade(ucl and may be run until the carbureter is suiciently heated on suchhigh grade fuel and muy be thereafter run on ordinary or low grade fuel.-4

4 My invention also includes means for preventing the operation of theignition devices of the engins during the time that the engine isreceiving its priming.

, invention also includes various improvements in the construction andcombination of parts, and has other-objects and advantageous features,which will appear from tbe following description of the means srning myinvention, with a diagrammatic illustration of the' sparking circuits.Fig. 2 is s. transverse vertical section taken centrally through one ofthe cylinders, on a plane indicated by the line 2-2, Fig. 1.

The engine shown is a four-cycle [our cylinder engine of usualconstruction, the cylinders 1 0, as ordinarily,

being srranged=in pairs, the exhaust outlets for the respectivocylinders appearing t 11 in Fig. 1, the

exhaust manifold piping 12 (see Fig. 2) being removed for cleamcss. Thecylinders receive the'. supply el combustible mixture through inletmanifold pipes 1,3 connedtcd h'y x11-connector 14 with a common supplypipe l5 and each opening into an inletchambcr 16 lcommon to a pair ofcylinders (Figs. l and 2). I Esch IUS cylinder has an exhaust-valve 17carried by l'stem or opemtingv-md 18, and also has sninlet valvelQ'cnrricd by a stem or operating-rod 20. The exhaust and inlet valvesare mechanically operated irl proper sequence -by a usual com-shaft 21carrying valve-operating cams i 22 to engage with the lower' ends ol thevalve stems to lift the valves against the tension ol usual strongvalvecoating thrust-springs 23 coiled about 'the vulve-stems andabutting against usual collars 24 thereon. The

lj-enginc has a main-shalt 'or crank-shaft 25 to which are l connectedpitmcn or piston-rods 26 -carrying pistons j 27 working in the cylinders10. Firing or ignition 'takes placolrom usual' spark plugs 28 from whichspark-circuit conductors 29 lead to respective segments of a distributorwhose. ornmon'contact terminal 3D is connected by a com mon'conductor 31to one terminal ol the secondary winding32 oi a spark-coil, the otherterminal o l' the spark-coil scconclflrjr 'boing shown as grounded at33. thus completing thecircuit.

Everything above pep V ticularly described,excepting alone the ci rcuit-breaker' S0 'or cut-out mentioned, i`susual and ordinary construction,;liut should be noted so us to properlyunderstand -my invention in its relation to the parts described.

.-Ths combustible mixture for the -engine is supplied by l carhurctorolthe construction shown, described 85 and clniincd in my above mentionedprior application. This carburetor has duplicate Iucl-rescrvoirs orfloatchsmbors 42 and 43, through which posses a common air-conduit 44which is continuous at its delivery oud with the delivery or enginesupply pipe 15 and is cou- 40 tinuous nt its intake end with an intakeconduit 45:

In 'operation great-er'prcssurc'at the intake end causes l current ofair to para through theek-conduit in the4 direction indicated by"arrows, 'such pressure b'eing caused, when the engine is running, byAthe suction or 45 low pressure produced by the engine. The two inde-lpendent [lont-chambers are provided for containing volatile liquid luclsof different grades orkinds. For

The'carbu'i'eteris provided `with an inwardly opening auxiliary air-inletvalve'dnormallyretained upon 4its seat by a spring 69.

According to m'y invention, preparatory to storting the engine, all ofthe cylinders are to be filled with combustible mixture. To thisendmeans are provided for blowing the combustible mixture through all ofthe cylinders concurrently, such means including l sourcel ol compressedair shown satin sir receiver or sir storage reservoir 70.4 o lar. as'thepresent invention is concerned, the supply of airheld undercompressiouiri tlc-Jeacrvoir 'IQ may be replenished in any convenientmanner. .For use in thus replenishing the air the reservoir is providedwith a plug or coupling part '71 liaving therein .an inwardly nripeningcheck, valveJZl- To produce a combustible mixture for starting theengine,

the compressed air ,from the reservoir is passedv through thecarburetor, and to assure thst a combustible mix'-, ture will be thenproduced niesus are provided for ascuring that the higher grade of fuelwill it that time b'e supplied tov the carburetor. For passing 'airthrough the carburetor 'an air-conduit 73 leads from the r`eservoir 70and opens into s passage 74 which communi- Cates, through a manually'operable oir controlling valve 75, with. a passage 76 which opens intothe airin'tako pipe 45 ol the carbureter. The air-controlling valve 15could be ol any preferred construction but is shown as of the puppettype 'cn'djls opening towards the air reservoir. This'valve has anactuating stem extending rearwardly t'the atmosphere through sn'ordinary packing gland as shown, the stern terminating ih a head bywhich the vilvs may be actuated. This valve is held upon itl b'y theprsure o! the 'air in the nir reservoir', aixd'il additionally retainedupon its seat and made to quichly-closs by l valve-closing thrust springshown as coiled about the vslvecte'm and acting upon the head of thevalve-stom.

The lli1r-iuutlre pipe 46 i! provided as usual with an air inlet opening77but in sdditxon thereto s vulve is provided lor controlling this slr'inlet opening, this valve beim dsosrn as an opening check-valve and inpressed lightly towards its seat by a thin spring as sho'wn, thuspresenting no appreciable obstacle to the ingress o! air in theoperation of the engine, but

closing unrler pressure o( the air from the reservoir to prevent theescape of this air to the atmosphere and to compel this air to passthrough the carbureter. As tho air from the sir reservoir passes throughthe carbureter it readily vaporizes the high grado'iuel which isprovided lor starting and forms s. combustible mixture which is passedinto'the cngine`c`ylinders and milde' to displace their former contentsuntil the cylinders becomo lillcd with the combustible mixture.

To allow the cylinders to till with combustible mixture, means areprovided for forcing open and holding open all ol the cylinder inletvalves 19 end also at the sometime allot the exhaust vslveii 1.7 untilthe cylin ders are thua'llled. Thus when the cylinder inlet and exhaustvulves are open and the air controlling valve is open, compressed airwill be b lown rom the-air reservoir through the carburetor wherein .itwill be carhureted to en explosive mixture, which will be 'blown throughthe cylinders, displacing their former contents and filling thecylinders with combustible mixture. When'the cylinders ha've becomelillcd `with combustible mixture the inlet and exhausthvalves and theair controlling valve are allowed to close, utter4 --which the engine ismade to startl by'igniting the mixturc in the cylinders in the properorder orsequence.

The means shown ,lor holding opeh the inlet and exhaust valves comprisevalve-opening cam-blocks- 79 carried hy s longitudinally slidahle barguided in hearings 8l on the engine llame. These' cambloeks have sashown a sloping or wedge-shaped portion for engaging beneaththevalve-stcrn collars 24 to raise the valves'. The bar BO'has elongatedopenings or slots to permit the valve stems 13 and 20 to pass throughthe bar without intcrlcring with the sliding movcmentof the bar, and avalve-lifting cam-block 79 is located at each nido laterally of cach' olauch slots (ses Fig. 3). The cams or wedges 7S) are shown as normallylocated in rear ol the valve stems, necessitating that the sliding har80 be moved forward to effect an opening of the engine vulves.'l Theliar 80 is shown ns having pi'vl otallconnection at Aits rear end withan intermediate lever 82 which is pivutally supported by a stationarypart ol th'e engine as shown. held alrite rearward position by athrust-spring 83 actning between theintormediate lever 82 andthe engineIranie. -The bsr 8.0 may be actuated 'at will, to cause tho'calns 79 toopen the enginevalves, by a pedal or foot-lever 8 4 connected to theintermediate lever 82 by a linlr or lconnecting rod B5. when the pedal84 is pressed the cams 75l Awill beactuated against the tension of thecnm-'bur-restoring spring 83 to lorca open all of the closed inlet andexhaust yalves 17 and 1.9. against the tension of the valve-closing'springs 23, and

"when the pedal is released all of the inletand exhaust valves notheld'open by the valve-operating cam: 22 will beclosed by theirvalve-closing' springs. "The intermediate lever 82 extends'downwardbeyond its connection .with the cxm-op'eratingbar 60 to engage with tbshead or outer erid oi the vslvefstem oi the air-J controlling valvo 76to hold this valve open while the inlet andhxbxust .valvesof the engineare held open.

.The bar 80 is normally When th pedal is released the air-controllingvolvo will be closed by its spring and. by the pressure ol aix' in thoreservoir. To form s proper combustible mixture for starting the engine,means are,provided lor automatically supplying the higher grade luel' orstarting iuel and for cutting off the lower grade iuelor ordinaryrunning fuel. Such means comprise e. valve-actuating pin 86 carried bythe slidable bar 80 at the rear of and in alinementl with the upper armof the-hell-cranlc lever 61.' When the bar 8O is moved forwardly to openthe enginewalves the pin 86 engages with the bell-crank lever to pushthe upperarm thereof forward, thereby,'through connections .containinglow grade or ordinary' running full, and its nozzle, is seen in Figs. 2,4 and 5. lt is usually desirable that the engine shrill not only begiven its initial or starting movement with high grade fuel, but that itshall continue-to use the high grade fuel until the care bureter shallhave becomo-suiliciently warned to attisactorily vaporize the ordinaryrunning fuel. Thcrofore, the nozzle-controlling valve 56 is not arrangedto be operated in its opposite direction oi rotation by the returnmovement of the bar S0, the pin 86 `then merely moving away from thebell-crank 61, as shown in Fig. 1, leaving the nozzle-'controlling valvethe position seen in Fig. 5. After a short period of running olthoengine thenozzle-controlling valve may be independently restored to itsformer position, to supply the ordi-- nary running fuel, by drawingbackward the handle G3. Means ere'providcd for preventing ignition whiletheV cylinders are being filled with combustible mixture. Such means usshown comprises a cutrout or circuit breaker for automatically openingthe battery circuit. The battry circuit conductor .40 ls connected to acontact spring o'r movable terminal 87 shown as c'arric-l by butelectrically insulated from a brise-plate 88 o which is connected thelbuttery circuit conductor L The plate 88 carries an adjustablestationary contact tonni 'nal 89 for coperating with the movableterminal 87.

The foot-lever is shown as extended below its lulcrurn lp'ivot andprovided with an insulating tip which normallyfengages the springContact terminal El? to lrolrl il; in contact with -the stationarycontact termnal't) undn thus to preserve the continuity ol the batterycircuit. However, when the pedal is pressed forward to xictuate theabove described devices for blowing a combustible mixture through thecylinders, the contact spring 87' is released and opens the batterycircuit, lenergizingl the spark-coil and preventing ignition takingplace until thebattery circuit is restahlished by the release of thepedal.

It is to be noted that allot the abovemamed inc i- I i ldentls lofoperation should take place their'proper sequence.' For example', it isobvious that sparking should be discontinued prior to the opening ol theaircontrolling valve., `n uclitis obvious that the 'sparking should notbe resumed until after mohair-controlling'valve has closed, nor untilafter the 'inlet and e'x-V haunt valves have been re'loasodby cams 79,it il Y preferable that air-controlling 'valve should not bo openeduntil alter the inlet and exhaust vulves' have heen opened-nt lenstsulliciently to provide s clear nud unobstructed voy through thecylinders so that the nir may pass reely through the carbureter toproduce su eflcient vaporizution. As shown in the drawings (Fig. l),when the loot-lever is depressed the c'ohlactspring 87 will be releasedand will open the battery circuit along' with the initial vulve-openingmovement ol the bar 80 and previously to the engagement of the,

' lever 82 with the stern ol the aincontroliing 'vlve 75 to open auchvalve. .As shown in the drawing-s, the inlet and exhaust valves willhave substantially completed their opening movement prior to the'sctuntion of tho l air-controlling valve 75; The nozzlerontroliing4valve l5 56 ivill be nctuuted, tosupply storting fuel to thocarbureter,along with tlie vulve-'opening movement ol' 4the bar 80. -Wllen thepednl is released the spring 83 'acts upon lire lever 82, lirst,incidentally. to release und pennit the closure ol theair-'controlli-.i'g valv'e 7.5, wond |ast,just alter the inlet andexhaust valves have been relensed hy the ca'ms 79. to depress thecontact spring 87 and rcstorethe battery circuit.

To start the engine tin.l perlnl is simply pressed down and held for nfew moments and then released. Ignition will then toko place inwhichever cylinder sparkying occurs,according ln the operativo positionof the distributor or sprk-controllel 39. Should the operative .positionhe such 'tlmt sperking'does-not occur, then .'spnrking may be caused tooccur by manigulation ol' the spark-controller in the usual n'mnner olspark adjustment. lter the linut ignition has loccurred, und. en initialstorting movement thereby given, the charges fin the other cylinderswill be tired successively in their l'aropr order, the engine thencontinuing to run in th ordinary manner by dmwing nir through thecarburetor mul atmospheric nininlet 77. Alter a short period of running::md consequent vmnnig of the cnrbureter, nrdinury running fuel may besubstituted for the starting luvl by operoting the nozzle-controllinghandle 63 nsuhove described.
